FIELD OF THE INVENTION

The present invention relates to small molecule potentiators of Cystic Fibrosis Transmembrane conductance Regulator (CFTR). This invention also relates to pharmaceutical compositions comprising the potentiators, optionally in combination with additional therapeutic agents, and methods of potentiating, in mammals, including humans, CFTR by administration of the small molecule CFTR potentiators. The present invention also relates to the treatment of cystic fibrosis and other disorders in mammals, including humans, with the CFTR potentiators. More particularly, this invention relates to 2,5,6,7-tetrasubstituted-7H-pyrrolo[2,3-d]pyrimidin-4-amine derivatives useful for the treatment of cystic fibrosis (CF), asthma, bronchiectasis, chronic obstructive pulmonary disease (COPD), constipation, Diabetes mellitus, dry eye disease, pancreatitis, rhinosinusitis, Sjögren's Syndrome, and other CFTR associated disorders.

BACKGROUND OF THE INVENTION

Cystic fibrosis (CF) is the most common lethal genetic disease affecting Caucasians. CF is an autosomal recessive disease with an incidence of between 1 in 2000 and 1 in 3000 live births (Cutting, G. R., Accurso, F., Ramsey, B. W., and Welsh, M. J., Online Metabolic & Molecular Bases of Inherited Disease, McGraw-Hill, 2013). There are over 70,000 people affected worldwide, of which approximately 33,000 are in the United States (www.cff.org/What-is-CF/About-Cystic-Fibrosis/). The hallmarks of CF are excessive mucus secretion and defective mucus clearance resulting in obstruction, infection and inflammation in the airways; pancreatic insufficiency; and elevated sweat chloride concentration. CF is a multisystem disease affecting the lungs, pancreas, and gastrointestinal, hepatobiliary, and reproductive tracts (R. D. Coakley et al., in Cystic Fibrosis, Eds. Hodson, M., Geddes, D., and Bush, A., Edward Arnold, Third Ed., 2007, pp. 59-68).

For most patients, there is a high burden of care for supportive therapies that do not address the root cause of the disease. Supportive therapies include physical airway clearance techniques, inhaled medications (mucolytics, antibiotics, and hypertonic saline), oral anti-inflammatory drugs, pancreatic enzyme replacements, and nutritional supplements (Cystic Fibrosis Foundation Patient Registry 2011 Annual Data Report to the Center Directors, Cystic Fibrosis Foundation, Bethesda, Md., 2012). The median age of survival for patients with cystic fibrosis is into the fourth decade of life.

Cystic fibrosis is caused by mutations in the gene for CFTR (Cystic Fibrosis Transmembrane conductance Regulator), an ion channel found in epithelia as well as other tissues. CFTR is found at the apical membrane of epithelial cells in the airways, intestine, pancreas, and sweat glands (G. R. Cutting, Accurso, F., Ramsey, B. W., and Welsh, M. J., Online Metabolic & Molecular Bases of Inherited Disease, McGraw-Hill, 2013). Mutations in CFTR have been classified into six types (Welsh, M. J., and Smith, A. E., Cell, 1993, 73, 1251-1254 and Sloane, P. A., and Rowe, S. M., Curr. Opin. Pulm. Med., 2010, 16, 591-597): 1) premature termination due to deletion, nonsense, or frameshift mutations, 2) defective trafficking out of the endoplasmic reticulum due to improper folding, 3) improper gating, 4) reduced conductance due to changes in the channel pore, 5) reduced production of channel due to altered splicing, and 6) increased endocytosis from the plasma membrane.

Nearly 2,000 different mutations in CFTR are known to cause CF. Deletion of Phe508 of CFTR (F508del) occurs in approximately 70% of CFTR alleles (Bobadilla, J. L. et al., Human Mutation, 2002, 19, 575-606). Approximately 50% of patients are F508del homozygotes and ca. 40% are heterozygotes so that at least one copy of F508del is present in about 90% of patients. G551D is the third most common mutation and is present in about 4% of patients (Cystic Fibrosis Foundation Patient Registry 2011 Annual Data Report to the Center Directors, Cystic Fibrosis Foundation, Bethesda, Md., 2012).

The F508del mutation causes loss of CFTR function due to both reduced channel density and impaired channel gating. Channel density at the apical membrane is reduced due to protein misfolding. Misfolded CFTR is recognized by cellular quality control mechanisms and degraded (Ward, C. L. and Kopito, R. R., J. Biol. Chem., 1994, 269, 25710-25718). F508del function is further reduced because it has a significantly reduced channel open probability (gating defect) (Dalemans, W. et al., Nature, 1991, 354, 526-528). The G551D mutation results in a protein with normal folding but impaired gating (Illek, B. et al., Am. J. Physiol., 1999, 277, C833-C839).

Small molecules called ‘correctors’ have been shown to reverse the folding/trafficking defect of F508del CFTR and increase the density of CFTR channels at the plasma membrane (Pedemonte, N. et al., J. Clin. Invest., 2005, 115, 2564-2571, Van Goor, F. et al., Am. J. Physiol. Lung Cell. Mol. Physiol., 2006, 290, L1117-1130, Van Goor, F. et al., Proc. Nat. Acad. Sci. USA, 2011, 108, 18843-18848). ‘Potentiators’ are small molecules that increase the channel open probability of mutant CFTR, reversing the gating defect. Pharmacological repair of F508del is thought to require at least a corrector and a potentiator to address the folding and gating defects while G551D may see benefit from a potentiator only.

Kalydeco® (ivacaftor, VX-770) is a marketed potentiator that improves the gating characteristics of G551D. In G551D patients, it substantially improved lung function (percent predicted FEV₁ increased 10-13%), allowed weight gain, and reduced the frequency of pulmonary exacerbations (Ramsey, B. W. et al., New Eng. J. Med., 2011, 365, 1663-1672, Davies, J. C. et al., Am. J. Resp. Crit. Care Med., 2013, 187, 1219-1225). Kalydeco® is also approved for people with G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N, and S549R mutations and application to other mutations including those with partial function is being investigated.

While monotherapy with Kalydeco® did not lead to any appreciable improvement in F508del homozygote patients (Flume, P. A. et al., Chest, 2012, 142, 718-724), a combination of a corrector (VX-809, lumacaftor or VX-661, tezacaftor) with Kalydeco® resulted in a modest improvement in lung function (percent predicted FEV₁ increased 3-4%) (Wainwright, C. E. et al., N. Engl. J. Med., 2015, 373, 220-231, Pilewski, J. M. et al., J. Cystic Fibrosis, 2015, 14, Suppl. 1, S1). The VX-809 plus Kalydeco® combination (called Orkambi®) is a marketed therapy for F508del homozygote patients.

For both the G551D and the F508del patient populations, improved therapies are expected to provide further benefit to patients. Most G551D patients are G551D/F508del compound heterozygotes and treatment with the combination of the corrector VX-661 plus Kalydeco® resulted in a further increase in lung function over Kalydeco® alone (Pilewski, J. M. et al., J. Cystic Fibrosis, 2015, 14, Suppl. 1, S1).

Mutations in CFTR that are associated with moderate CFTR dysfunction are also evident in patients with conditions that share certain disease manifestations with cystic fibrosis but do not meet the diagnostic criteria for cystic fibrosis. In these patients, CFTR dysfunction at epithelial cell layers can occur and give rise to abnormal mucus and endocrine secretions that are similar to those that characterize cystic fibrosis. CFTR dysfunction may also be acquired. Chronic inhalation of particulate irritants, including cigarette smoke, pollution, and dust can result in reduced CFTR ion-channel activity.

Modulation of CFTR activity may also be beneficial for other diseases not directly caused by mutations in CFTR, such as secretory diseases and other protein folding diseases mediated by CFTR. CFTR regulates chloride and bicarbonate flux across the epithelia of many cells to control fluid movement, protein solubilization, mucus viscosity, and enzyme activity. Defects in CFTR can cause blockage of the airway or ducts in many organs, including the liver and pancreas. Potentiators are compounds that enhance the gating activity of CFTR present in the cell membrane. Any disease which involves thickening of the mucus, impaired fluid regulation, impaired mucus clearance, or blocked ducts leading to inflammation and tissue destruction could be a candidate for potentiators. Therefore, there exists a significant therapeutic need for novel small molecules that act as potentiators of CFTR.

In addition to cystic fibrosis, CFTR-related diseases or other diseases which may benefit from modulation of CFTR activity include, but are not limited to, asthma, bronchiectasis, chronic obstructive pulmonary disease (COPD), constipation, diabetes mellitus, dry eye disease, pancreatitis, rhinosinusitis, and Sjögren's Syndrome.

Definitions

The term “alkyl” refers to a linear or branched-chain saturated hydrocarbyl substituent (i.e., a substituent obtained from a hydrocarbon by removal of a hydrogen); in one embodiment from one to six carbon atoms (i.e., C₁-C₆alkyl). Examples of such substituents include methyl, ethyl, propyl (including n-propyl and isopropyl), butyl (including n-butyl, isobutyl, sec-butyl and tert-butyl), pentyl, isoamyl, hexyl and the like.

The term “haloalkyl” refers to an alkyl in which at least one hydrogen on the alkyl is replaced with a halogen atom. The term “C₁-C₆ haloalkyl” refers to a C₁-C₆ alkyl group, as defined herein, in which one, two, three, four, five, or six hydrogen atoms are replaced by halogen. In certain embodiments in which two or more hydrogen atoms are replaced with halogen atoms, the halogen atoms are all the same as one another. In other embodiments in which two or more hydrogen atoms are replaced with halogen atoms, the halogen atoms are not all the same as one another. Examples of haloakyls include: chloromethyl, fluoromethyl, difluoromethyl, trifluoromethyl, 1, 1-difluoroethyl, 2-fluoroethyl, 2,2-difluoroethyl, 2-chloro-3-fluoropentyl, and the like.

The term “alkoxy” refers to a linear or branched-chain saturated hydrocarbyl substituent (i.e., a substituent obtained from a hydrocarbon by removal of a hydrogen) which is in turn attached to an oxygen atom; in one embodiment from one to six carbon atoms (i.e., C₁-C₆alkoxy). Examples of such substituents include methoxy, ethoxy, propoxy (including n-propoxy and isopropoxy), butoxy (including n-butoxy, isobutoxy, sec-butoxy and tert-butoxy), pentoxy and the like.

The term “cycloalkyl” refers to a carbocyclic substituent obtained by removing a hydrogen atom from a saturated carbocyclic molecule and having the specified number of carbon atoms. In one embodiment, a cycloalkyl substituent has three to seven carbon atoms (i.e., C₃-C₇cycloalkyl). Examples of cycloalkyl include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. The term “cycloalkyl” includes mono-, bi- and tricyclic saturated carbocycles, as well as bridged and fused ring carbocycles, as well as spiro-fused ring systems.

As used herein, the term “heterocycloalkyl” refers to a monocyclic ring system containing the heteroatoms N, O or S(O)_(n) as specified. The term “heterocycloalkyl” refers to a substituent obtained by removing a hydrogen from a saturated or partially saturated ring structure containing the specified number of ring atoms, wherein at least one of the ring atoms is a heteroatom (i.e. oxygen, nitrogen, or sulfur), with the remaining ring atoms being independently selected from the group consisting of carbon, oxygen, nitrogen, and sulfur. If the heterocycloalkyl substituent is in turn substituted with a group or substituent, the group or substituent may be bound to a nitrogen heteroatom, or it may be bound to a ring carbon atom, as appropriate. In some instances, the number of atoms in a cyclic substituent containing one or more heteroatoms (i.e., heteroaryl or heterocycloalkyl) is indicated by the prefix “x to y membered”, wherein x is the minimum and y is the maximum number of atoms forming the cyclic moiety of the substituent. Thus, for example, “four to seven membered heterocycloalkyl” refers to a heterocycloalkyl containing from four to seven atoms, including one or more heteroatoms, in the cyclic moiety of the heterocycloalkyl. Examples of single-ring heterocycloalkyls include azetidinyl, oxetanyl, thietanyl, dihydrofuranyl, tetrahydrofuranyl, dihydrothiophenyl, tetrahydrothiophenyl, pyrrolinyl, pyrrolidinyl, imidazolinyl, imidazolidinyl, pyrazolinyl, pyrazolidinyl, thiazolinyl, isothiazolinyl, thiazolidinyl, isothiazolidinyl, dihydropyranyl, piperidinyl, morpholinyl, piperazinyl, azepinyl, oxepinyl, and diazepinyl.

The term “heteroaryl” refers to an aromatic ring structure containing the specified number of ring atoms in which at least one of the ring atoms is a heteroatom (i.e. oxygen, nitrogen, or sulfur), with the remaining ring atoms being independently selected from the group consisting of carbon, oxygen, nitrogen, and sulfur. A five to six membered heteroaryl is an aromatic ring system which has five or six ring atoms with at least one of the ring atoms being N, O or S(O)_(n). Similarly, a five to ten membered heteroaryl is an aromatic ring system which has five to ten ring atoms with at least one of the ring atoms being N, O or S(O)_(n). A heteroaryl may be a single ring or 2 fused rings.

Examples of heteroaryl substituents include six membered ring substituents such as pyridinyl, pyrazinyl, pyrimidinyl, and pyridazinyl; five membered ring substituents such as triazolyl, imidazolyl, furanyl, thiophenyl, pyrazolyl, oxazolyl, isoxazolyl, thiazolyl, 1,2,3-, 1,2,4-, 1,2,5-, or 1,3,4-oxadiazolyl and isothiazolyl; 6/5-membered fused ring substituents such as benzothiofuranyl, isobenzothiofuranyl, benzisoxazolyl, benzoxazolyl, purinyl, and anthranilyl; and 6/6-membered fused rings such as quinolinyl, isoquinolinyl, cinnolinyl, quinazolinyl, and 1,4-benzoxazinyl. In a group that has a heteroaryl substituent, the ring atom of the heteroaryl substituent that is bound to the group may be the at least one heteroatom, or it may be a ring carbon atom, where the ring carbon atom may be in the same ring as the at least one heteroatom or where the ring carbon atom may be in a different ring from the at least one heteroatom. Similarly, if the heteroaryl substituent is in turn substituted with a group or substituent, the group or substituent may be bound to the at least one heteroatom, or it may be bound to a ring carbon atom, where the ring carbon atom may be in the same ring as the at least one heteroatom or where the ring carbon atom may be in a different ring from the at least one heteroatom. The term “heteroaryl” also includes pyridinyl N-oxides and groups containing a pyridine N-oxide ring. Examples of 2-fused-ring heteroaryls include indolizinyl, pyranopyrrolyl, 4H-quinolizinyl, purinyl, naphthyridinyl, pyridopyridinyl (including pyrido[3,4-b]-pyridinyl, pyrido[3,2-b]-pyridinyl, or pyrido[4, 3-5]-pyridinyl), pyrrolopyridinyl, pyrazolopyridinyl and imidazothiazolyl and pteridinyl.

Other examples of fused-ring heteroaryls include benzo-fused heteroaryls such as indolyl, isoindolyl, indoleninyl, isoindazolyl, benzazinyl (including quinolinyl or isoquinolinyl), phthalazinyl, quinoxalinyl, benzodiazinyl (including cinnolinyl or quinazolinyl), benzopyranyl, benzothiopyranyl, benzoxazolyl, indoxazinyl, anthranilyl, benzodioxolyl, benzodioxanyl, benzoxadiazolyl, benzofuranyl, isobenzofuranyl, benzothienyl, isobenzothienyl, benzothiazolyl, benzothiadiazolyl, benzimidazolyl, benzotriazolyl, benzoxazinyl, benzisoxazinyl. The foregoing groups, as derived from the groups listed above, may be C-attached or N-attached where such is possible. For instance, a group derived from pyrrole may be pyrrol-1-yl (N-attached) or pyrrol-3-yl (C-attached). Further, a group derived from imidazole may be imidazol-1-yl (N-attached) or imidazol-2-yl (C-attached).

The term “halo” or “halogen” refers to fluoro (which may be depicted as —F), chloro (which may be depicted as —Cl), bromo (which may be depicted as —Br), or iodo (which may be depicted as —I).

The term “hydrogen” refers to a hydrogen substituent, and may be depicted as —H.

The term “hydroxy” or “hydroxyl” refers to —OH. Compounds bearing a carbon to which one or more hydroxyl substituents are attached include, for example, alcohols, enols and phenol.

The term “phenyl” refers to an aromatic ring having the radical —C₆H₅, derived from benzene by removal of a hydrogen atom. Phenyl may be optionally fused with a five or six membered cycloalkyl or heterocycloalkyl ring to form bicyclic compounds. Examples of these bicyclic compounds include 1,2,3,4-tetrahydronaphthalene, 2,3-dihydrobenzo[1,4]oxazine, 2,3-dihydro-1H-indene, isoindoline, and 2,3-dihydrobenzo[1,4]dioxine.

If substituents are described as being “independently selected” from a group, each instance of a substituent is selected independent of the other. Each substituent therefore may be identical to or different from the other substituent(s).

As used herein, the term “formula I”, “formula (I)”, “Formula (I)”, or “Formula I” may be referred to as a “compound(s) of the invention”. Such terms are also defined to include all forms of the compound of formula I, including hydrates, solvates, isomers, crystalline and noncrystalline forms, isomorphs, polymorphs, and metabolites thereof. For example, the compounds of the invention, or pharmaceutically acceptable salts thereof, may exist in unsolvated and solvated forms. When the solvent or water is tightly bound, the complex will have a well-defined stoichiometry independent of humidity. When, however, the solvent or water is weakly bound, as in channel solvates and hygroscopic compounds, the water/solvent content will be dependent on humidity and drying conditions. In such cases, non-stoichiometry will be the norm.

The compounds of the invention may exist as clathrates or other complexes. Included within the scope of the invention are complexes such as clathrates, drug-host inclusion complexes wherein the drug and host are present in stoichiometric or non-stoichiometric amounts. Also included are complexes of the compounds of the invention containing two or more organic and/or inorganic components which may be in stoichiometric or non-stoichiometric amounts. The resulting complexes may be ionized, partially ionized, or non-ionized. For a review of such complexes, see J. Pharm. Sci., 64 (8), 1269-1288, Haleblian, J. K. (August 1975).

The compounds of the invention may have asymmetric carbon atoms. The carbon-carbon bonds of the compounds of the invention may be depicted herein

using a solid line (

), a solid wedge (

), or a dotted wedge (

). The use of a solid line to depict bonds to asymmetric carbon atoms is meant to indicate that all possible stereoisomers (e.g., specific enantiomers, racemic mixtures, etc.) at that carbon atom are included. The use of either a solid or dotted wedge to depict bonds to asymmetric carbon atoms is meant to indicate that only the stereoisomer shown is meant to be included. It is possible that compounds of Formula I may contain more than one asymmetric carbon atom. In those compounds, the use of a solid line to depict bonds to asymmetric carbon atoms is meant to indicate that all possible stereoisomers are meant to be included. For example, unless stated otherwise, it is intended that the compounds of Formula I can exist as enantiomers and diastereomers or as racemates and mixtures thereof. The use of a solid line to depict bonds to one or more asymmetric carbon atoms in a compound of Formula I and the use of a solid or dotted wedge to depict bonds to other asymmetric carbon atoms in the same compound is meant to indicate that a mixture of diastereomers is present.

Stereoisomers of Formula I include cis and trans isomers, optical isomers such as R and S enantiomers, diastereomers, geometric isomers, rotational isomers, conformational isomers, and tautomers of the compounds of the invention, including compounds exhibiting more than one type of isomerism; and mixtures thereof (such as racemates and diastereomeric pairs). Also included are acid addition or base addition salts wherein the counterion is optically active, for example, D-lactate or L-lysine, or racemic, for example, DL-tartrate or DL-arginine.

When any racemate crystallizes, crystals of two different types are possible. The first type is the racemic compound (true racemate) referred to above wherein one homogeneous form of crystal is produced containing both enantiomers in equimolar amounts. The second type is the racemic mixture or conglomerate wherein two forms of crystal are produced in equimolar amounts each comprising a single enantiomer.

The present invention comprises the tautomeric forms of compounds of the invention. Where structural isomers are interconvertible via a low energy barrier, tautomeric isomerism (‘tautomerism’) can occur. This can take the form of proton tautomerism in compounds of the invention containing, for example, an imino, keto, or oxime group, or so-called valence tautomerism in compounds which contain an aromatic moiety. It follows that a single compound may exhibit more than one type of isomerism. The various ratios of the tautomers in solid and liquid form are dependent on the various substituents on the molecule as well as the particular crystallization technique used to isolate a compound.

Examples of types of potential tautomerisms shown by the compounds of the invention include hydroxypyridine

pyridone; amide

hydroxyl-imine and keto

enol tautomersims:

The compounds of this invention may be used in the form of salts derived from inorganic or organic acids. Depending on the particular compound, a salt of the compound may be advantageous due to one or more of the salt's physical properties, such as enhanced pharmaceutical stability in differing temperatures and humidities, or a desirable solubility in water or oil. In some instances, a salt of a compound also may be used as an aid in the isolation, purification, and/or resolution of the compound. Where a salt is intended to be administered to a patient (as opposed to, for example, being used in an in vitro context), the salt preferably is pharmaceutically acceptable. The term “pharmaceutically acceptable salt” refers to a salt prepared by combining a compound of formula I with an acid whose anion, or a base whose cation, is generally considered suitable for human consumption. Pharmaceutically acceptable salts are particularly useful as products of the methods of the present invention because of their greater aqueous solubility relative to the parent compound. For use in medicine, the salts of the compounds of this invention are non-toxic “pharmaceutically acceptable salts”. Salts encompassed within the term “pharmaceutically acceptable salts” refer to non-toxic salts of the compounds of this invention which are generally prepared by reacting the free base with a suitable organic or inorganic acid.

Suitable pharmaceutically acceptable acid addition salts of the compounds of the present invention when possible include those derived from inorganic acids, such as hydrochloric, hydrobromic, hydrofluoric, boric, fluoroboric, phosphoric, metaphosphoric, nitric, carbonic, sulfonic, and sulfuric acids, and organic acids such as acetic, benzenesulfonic, benzoic, citric, ethanesulfonic, fumaric, gluconic, glycolic, isothionic, lactic, lactobionic, maleic, malic, methanesulfonic, trifluoromethanesulfonic, succinic, toluenesulfonic, tartaric, and trifluoroacetic acids. Suitable organic acids generally include, for example, aliphatic, cycloaliphatic, aromatic, araliphatic, heterocyclic, carboxylic, and sulfonic classes of organic acids. Specific examples of suitable organic acids include acetate, trifluoroacetate, formate, propionate, succinate, glycolate, gluconate, digluconate, lactate, malate, tartaric acid, citrate, ascorbate, glucuronate, maleate, fumarate, pyruvate, aspartate, glutamate, benzoate, anthranilic acid, stearate, salicylate, p-hydroxybenzoate, phenylacetate, mandelate, embonate (pamoate), methanesulfonate, ethanesulfonate, benzenesulfonate, pantothenate, toluenesulfonate, 2-hydroxyethanesulfonate, sufanilate, cyclohexylaminosulfonate, P-hydroxybutyrate, galactarate, galacturonate, adipate, alginate, butyrate, camphorate, camphorsulfonate, cyclopentanepropionate, dodecylsulfate, glycoheptanoate, glycerophosphate, heptanoate, hexanoate, nicotinate, 2-naphthalesulfonate, oxalate, palmoate, pectinate, 3-phenylpropionate, picrate, pivalate, thiocyanate, and undecanoate.

Furthermore, where the compounds of the invention carry an acidic moiety, suitable pharmaceutically acceptable salts thereof may include alkali metal salts, i.e., sodium or potassium salts; alkaline earth metal salts, e.g., calcium or magnesium salts; and salts formed with suitable organic ligands, e.g., quaternary ammonium salts. In another embodiment, base salts are formed from bases which form non-toxic salts, including aluminum, arginine, benzathine, choline, diethylamine, diolamine, glycine, lysine, meglumine, olamine, tromethamine and zinc salts.

Organic salts may be made from secondary, tertiary or quaternary amine salts, such as tromethamine, diethylamine, N, N′-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine (N-methylglucamine), and procaine. Basic nitrogen-containing groups may be quaternized with agents such as lower alkyl (C₁-C₆) halides (e.g. methyl, ethyl, propyl, and butyl chlorides, bromides, and iodides), dialkyl sulfates (i.e., dimethyl, diethyl, dibutyl, and diamyl sulfates), long chain halides (e.g., decyl, lauryl, myristyl, and stearyl chlorides, bromides, and iodides), arylalkyl halides (e.g., benzyl and phenethyl bromides), and others.

In one embodiment, hemisalts of acids and bases may also be formed, for example, hemisulfate and hemicalcium salts.

Also within the scope of the present invention are so-called “prodrugs” of the compound of the invention. Thus, certain derivatives of the compound of the invention which may have little or no pharmacological activity themselves can, when administered into or onto the body, be converted into the compound of the invention having the desired activity, for example, by hydrolytic cleavage. Such derivatives are referred to as “prodrugs”. Further information on the use of prodrugs may be found in “Pro-drugs as Novel Delivery Systems”, Vol. 14, ACS Symposium Series (T. Higuchi and V. Stella, Eds.), American Chemical Society, 1975 Washington, D.C. and “Bioreversible Carriers in Drug Design”, Pergamon Press, 1987 (E. B. Roche, Ed.) American Pharmaceutical Association. Prodrugs in accordance with the invention can, for example, be produced by replacing appropriate functionalities present in the compounds of any of formula I with certain moieties known to those skilled in the art as “pro-moieties” as described, for example, in Bundgaard, H. 1985. Design of Prodrugs. New York: Elsevier.

The present invention also includes isotopically labeled compounds, which are identical to those recited in formula I, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹¹C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively.

Compounds of the present invention, prodrugs thereof, and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically labeled compounds of the present invention, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds of formula I of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the Schemes and/or in the Examples and Preparations below, by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

DETAILED DESCRIPTION OF THE INVENTION

Typically, a compound of the invention is administered in an amount effective to treat a condition as described herein. The compounds of the invention are administered by any suitable route in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. Therapeutically effective doses of the compounds required to treat the progress of the medical condition are readily ascertained by one of ordinary skill in the art using preclinical and clinical approaches familiar to the medicinal arts.

The term “treating”, as used herein, unless otherwise indicated, means reversing, alleviating, inhibiting the progress of, or preventing the disorder or condition to which such term applies, or one or more symptoms of such disorder or condition. The term “treatment”, as used herein, unless otherwise indicated, refers to the act of treating as “treating” is defined immediately above. The term “treating” also includes adjuvant and neo-adjuvant treatment of a subject. The compounds of the invention may be administered orally. Oral administration may involve swallowing, so that the compound enters the gastrointestinal tract, or buccal or sublingual administration may be employed, by which the compound enters the blood stream directly from the mouth.

In another embodiment, the compounds of the invention may also be administered directly into the blood stream, into muscle, or into an internal organ. Suitable means for parenteral administration include intravenous, intraarterial, intraperitoneal, intrathecal, intraventricular, intraurethral, intrasternal, intracranial, intramuscular and subcutaneous.

In another embodiment, the compounds of the invention can also be administered intranasally or by inhalation. In another embodiment, the compounds of the invention may be administered rectally or vaginally. In another embodiment, the compounds of the invention may also be administered directly to the eye or ear.

The dosage regimen for the compounds and/or compositions containing the compounds is based on a variety of factors, including the type, age, weight, sex and medical condition of the patient; the severity of the condition; the route of administration; and the activity of the particular compound employed. Thus the dosage regimen may vary widely. Dosage levels of the order from about 0.01 mg to about 100 mg per kilogram of body weight per day are useful in the treatment of the above-indicated conditions. In one embodiment, the total daily dose of a compound of the invention (administered in single or divided doses) is typically from about 0.01 to about 100 mg/kg. In another embodiment, the total daily dose of the compound of the invention is from about 0.1 to about 50 mg/kg, and in another embodiment, from about 0.5 to about 30 mg/kg (i.e., mg compound of the invention per kg body weight). In one embodiment, dosing is from 0.01 to 10 mg/kg/day. In another embodiment, dosing is from 0.1 to 1.0 mg/kg/day. Dosage unit compositions may contain such amounts or submultiples thereof to make up the daily dose. In many instances, the administration of the compound will be repeated a plurality of times in a day (typically no greater than 4 times). Multiple doses per day typically may be used to increase the total daily dose, if desired.

For oral administration, the compositions may be provided in the form of tablets containing from about 0.01 mg to about 500 mg of the active ingredient, or in another embodiment, from about 1 mg to about 100 mg of active ingredient. Intravenously, doses may range from about 0.1 to about 10 mg/kg/minute during a constant rate infusion.

Suitable subjects according to the present invention include mammalian subjects. Mammals according to the present invention include, but are not limited to, canine, feline, bovine, caprine, equine, ovine, porcine, rodents, lagomorphs, primates, and the like, and encompass mammals in utero. In one embodiment, humans are suitable subjects. Human subjects may be of either gender and at any stage of development.

In another embodiment, the invention comprises the use of one or more compounds of the invention for the preparation of a medicament for the treatment of the conditions recited herein.

For the treatment of the conditions referred to above, the compound of the invention can be administered as compound per se. Alternatively, pharmaceutically acceptable salts are suitable for medical applications because of their greater aqueous solubility relative to the parent compound.

In another embodiment, the present invention comprises pharmaceutical compositions. Such pharmaceutical compositions comprise a compound of the invention presented with a pharmaceutically acceptable carrier. The carrier can be a solid, a liquid, or both, and may be formulated with the compound as a unit-dose composition, for example, a tablet, which can contain from 0.05% to 95% by weight of the active compounds. A compound of the invention may be coupled with suitable polymers as targetable drug carriers. Other pharmacologically active substances can also be present.

The compounds of the present invention may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. The active compounds and compositions, for example, may be administered orally, rectally, parenterally, or topically.

Oral administration of a solid dose form may be, for example, presented in discrete units, such as hard or soft capsules, pills, cachets, lozenges, or tablets, each containing a predetermined amount of at least one compound of the present invention.

In another embodiment, the oral administration may be in a powder or granule form. In another embodiment, the oral administration may be in a spray-dried dispersion. In another embodiment, the oral dose form is sub-lingual, such as, for example, a lozenge. In such solid dosage forms, the compounds of formula I are ordinarily combined with one or more adjuvants. Such capsules or tablets may contain a controlled-release formulation. In the case of capsules, tablets, and pills, the dosage forms also may comprise buffering agents or may be prepared with enteric coatings.

In another embodiment, oral administration may be in a liquid dose form. Liquid dosage forms for oral administration include, for example, pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs containing inert diluents commonly used in the art (e.g., water). Such compositions also may comprise adjuvants, such as wetting, emulsifying, suspending, flavoring (e.g., sweetening), and/or perfuming agents.

In another embodiment, the present invention comprises a parenteral dose form. “Parenteral administration” includes, for example, subcutaneous injections, intravenous injections, intraperitoneal injections, intramuscular injections, intrasternal injections, and infusion. Injectable preparations (e.g., sterile injectable aqueous or oleaginous suspensions) may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents.

In another embodiment, the present invention comprises a topical dose form. “Topical administration” includes, for example, transdermal administration, such as via transdermal patches or iontophoresis devices, intraocular administration, or intranasal or inhalation administration. Compositions for topical administration also include, for example, topical gels, sprays, ointments, and creams. A topical formulation may include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. When the compounds of this invention are administered by a transdermal device, administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety.

Typical formulations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, dusting powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibers, bandages and microemulsions. Liposomes may also be used. Typical carriers include alcohol, water, mineral oil, liquid petrolatum, white petrolatum, glycerin, polyethylene glycol and propylene glycol. Penetration enhancers may be incorporated; see, for example, J. Pharm. Sci., 88 (10), 955-958, by Finnin and Morgan (October 1999).

Formulations suitable for topical administration to the eye include, for example, eye drops wherein the compound of this invention is dissolved or suspended in a suitable carrier. A typical formulation suitable for ocular or aural administration may be in the form of drops of a micronized suspension or solution in isotonic, pH-adjusted, sterile saline. Other formulations suitable for ocular and aural administration include ointments, biodegradable (e.g., absorbable gel sponges, collagen) and nonbiodegradable (e.g., silicone) implants, wafers, lenses and particulate or vesicular systems, such as niosomes or liposomes. A polymer such as cross-linked polyacrylic acid, polyvinyl alcohol, hyaluronic acid, a cellulosic polymer, for example, (hydroxypropyl)methyl cellulose, hydroxyethyl cellulose, or methyl cellulose, or heteropolysaccharide polymer, for example, gelan gum, may be incorporated together with a preservative, such as benzalkonium chloride. Such formulations may also be delivered by iontophoresis.

For intranasal administration or administration by inhalation, the active compounds of the invention are conveniently delivered in the form of a solution or suspension from a pump spray container that is squeezed or pumped by the patient or as an aerosol spray, delivered from a pressurized container or a nebulizer with the use of a suitable propellant. Formulations suitable for intranasal administration are typically administered in the form of a dry powder (either alone, as a mixture, for example, in a dry blend with lactose, or as a mixed component particle, for example, mixed with phospholipids, such as phosphatidylcholine) from a dry powder inhaler or as an aerosol spray from a pressurized container, pump, spray, atomizer (preferably an atomizer using electrohydrodynamics to produce a fine mist), or nebulizer, with or without the use of a suitable propellant, such as 1,1,1,2-tetrafluoroethane or 1,1,1,2,3,3,3-heptafluoropropane. For intranasal use, the powder may comprise a bioadhesive agent, for example, chitosan or cyclodextrin.

In another embodiment, the present invention comprises a rectal dose form. Such rectal dose form may be in the form of, for example, a suppository. Cocoa butter is a traditional suppository base, but various alternatives may be used as appropriate.

Other carrier materials and modes of administration known in the pharmaceutical art may also be used. Pharmaceutical compositions of the invention may be prepared by any of the well-known techniques of pharmacy, such as effective formulation and administration procedures. The above considerations in regard to effective formulations and administration procedures are well known in the art and are described in standard textbooks. Formulation of drugs is discussed in, for example, Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pa., 1975; Lieberman et al., Eds., Pharmaceutical Dosage Forms, Marcel Dekker, New York, N.Y., 1980; and Kibbe et al., Eds., Handbook of Pharmaceutical Excipients (3rd ed.), American Pharmaceutical Association, Washington, 2000.

The compounds of the present invention can be used, alone or in combination with other therapeutic agents, in the treatment of various conditions or disease states. The compound(s) of the present invention and other therapeutic agent(s) may be may be administered simultaneously (either in the same dosage form or in separate dosage forms) or sequentially.

Two or more compounds may be administered simultaneously, concurrently or sequentially. Additionally, simultaneous administration may be carried out by mixing the compounds prior to administration or by administering the compounds at the same point in time but at different anatomic sites or using different routes of administration.

The phrases “concurrent administration”, “co-administration”, “simultaneous administration,” and “administered simultaneously” mean that the compounds are administered in combination.

The present invention includes the use of a combination of a CFTR potentiator compound as provided in Formula I and one or more additional pharmaceutically active agent(s). If a combination of active agents is administered, then they may be administered sequentially or simultaneously, in separate dosage forms or combined in a single dosage form. Accordingly, the present invention also includes pharmaceutical compositions comprising an amount of: (a) a first agent comprising a compound of Formula I or a pharmaceutically acceptable salt of the compound; (b) a second pharmaceutically active agent; (c) optionally a third pharmaceutically active agent; and (d) a pharmaceutically acceptable carrier, vehicle or diluent.

Various pharmaceutically active agents may be selected for use in conjunction with the compounds of Formula I, depending on the disease, disorder, or condition to be treated. For example, a pharmaceutical composition for use in treating Cystic Fibrosis may comprise a compound of Formula I or a pharmaceutically acceptable salt thereof, together with one or more agents such as a CFTR modulator, for example another CFTR potentiator, a CFTR corrector, including a CAL (CFTR-associated ligand) inhibitor, a CFTR Production corrector or read-through agent, a CFTR stabilizer, including a CFTR-Dab2 (Disabled homolog 2) inhibitor, or a CFTR amplifier; an epithelial sodium channel (ENaC) inhibitor/blocker; an oligonucleotide patch; an autophagy inducer; a proteostasis modulator, including a histone deacetylase (HDAC) inhibitor; or supportive therapies such as a mucolytic agent, a bronchodilator, an antibiotic, an anti-infective agent, an anti-inflammatory agent, an anticholinergic, a mast cell stabilizer, a corticosteroid, a nutritional agent, or an enzyme replacement.

A combination can include more than one agent from a particular class of agents; for example, a combination of a compound of Formula I with two or more CFTR correctors.

General Synthetic Schemes

The compounds of the invention may be prepared by any method known in the art for the preparation of compounds of analogous structure. In particular, the compounds of the invention can be prepared by the procedures described by reference to the Schemes that follow, or by the specific methods described in the Examples, or by similar processes to either.

The skilled person will appreciate that the experimental conditions set forth in the schemes that follow are illustrative of suitable conditions for effecting the transformations shown, and that it may be necessary or desirable to vary the precise conditions employed for the preparation of compounds of Formula (I). It will be further appreciated that it may be necessary or desirable to carry out the transformations in a different order from that described in the schemes, or to modify one or more of the transformations, to provide the desired compound of the invention.

All of the derivatives of Formula I can be prepared by the procedures described in the general methods presented below or by routine modifications thereof. The present invention also encompasses any one or more of these processes for preparing the derivatives of Formula I, in addition to any novel intermediates used therein. The person skilled in the art will appreciate that the following reactions may be heated thermally or under microwave irradiation.

The routes below, including those mentioned in the Examples and Preparations, illustrate methods of synthesising compounds of Formula I. The skilled person will appreciate that the compounds of the invention, and intermediates thereto, could be made by methods other than those specifically described herein, for example by adaptation of the methods described herein, for example by methods known in the art. Suitable guides to synthesis, functional group interconversions, use of protecting groups, etc., are for example: “Comprehensive Organic Transformations” by R C Larock, VCH Publishers Inc. (1989); Advanced Organic Chemistry” by J. March, Wiley Interscience (1985); “Designing Organic Synthesis” by S Warren, Wiley Interscience (1978); “Organic Synthesis—The Disconnection Approach” by S Warren, Wiley Interscience (1982); “Guidebook to Organic Synthesis” by RK Mackie and DM Smith, Longman (1982); “Protective Groups in Organic Synthesis” by TW Greene and PGM Wuts, John Wiley and Sons, Inc. (1999); and “Protecting Groups” by PJ Kocienski, Georg Thieme Verlag (1994); and any updated versions of said standard works.

In addition, the skilled person will appreciate that it may be necessary or desirable at any stage in the synthesis of compounds of the invention to protect one or more sensitive groups, so as to prevent undesirable side reactions. In particular, it may be necessary or desirable to protect amino or carboxylic acid groups. The protecting groups used in the preparation of the compounds of the invention may be used in a conventional manner. See, for example, those described in ‘Greene's Protective Groups in Organic Synthesis’ by Theodora W Greene and Peter G M Wuts, fifth edition, (John Wiley and Sons, 2014), incorporated herein by reference, which also describes methods for the removal of such groups.

In the general synthetic methods below, unless otherwise specified, the substituents are as defined above with reference to the compounds of Formula (I) above. Where ratios of solvents are given, the ratios are by volume unless otherwise specified.

The compounds of the invention may be prepared by any method known in the art for the preparation of compounds of analogous structure. In particular, the compounds of the invention can be prepared by the procedures described by reference to the Schemes that follow, or by the specific methods described in the Examples, or by similar processes to either.

The skilled person will appreciate that the experimental conditions set forth in the schemes that follow are illustrative of suitable conditions for effecting the transformations shown, and that it may be necessary or desirable to vary the precise conditions employed for the preparation of compounds of Formula I.

According to a first process, compounds of Formula (IC) (where R²=CN) may be prepared from compounds of Formulae (IA) and (IB) as illustrated by Scheme 1.

In Scheme 1, compound of the Formula (IA) is converted to a compound of Formula (IB) wherein Hal is chloro, bromo or iodo (preferably bromo) by treatment with a suitable halogenating agent such as N-(Hal)succinimide, preferably NBS, in a suitable solvent, such as DCM or DMF at an appropriate temperature such as 0° C. A skilled person also knows that alternative methods for specifically introducing a suitable halogen group such as Br are achievable using alternative reagents, solvents and temperatures. A compound of Formula (IB) is converted into a compound of Formula (IC) by treatment with a suitable organometallic source of cyanide such as Zn(CN)₂ or CuCN in the presence of a suitable catalyst, such as Pd(dppf)Cl₂ (or Pd₂(dba)₃ plus dppf) in a suitable solvent, such as DMF or NMP at a suitable temperature. A skilled person also knows that alternative organometallic coupling strategies can be used involving alternative coupling partners, metals and solvent combinations. It is well understood by a skilled person that a compound of the Formula (IB) is prepared and isolated as described above or prepared in situ without isolation in a sequential reaction strategy leading to a compound of Formula (IC).

X-Ray Crystallography Methods

The following methods were used to obtain X-Ray crystallography data for several compounds.

Single Crystal X-Ray Analysis for Example 27.

Data collection was performed on a Bruker APEX diffractometer at room temperature. Data collection consisted of omega and phi scans. The structure was solved by direct methods using SHELX software suite in the Monoclinic class space group C2/c. The structure was subsequently refined by the full-matrix least squares method. All non-hydrogen atoms were found and refined using anisotropic displacement parameters.

The hydrogen atoms located on nitrogen were found from the Fourier difference map and refined with distances restrained. The remaining hydrogen atoms were placed in calculated positions and were allowed to ride on their carrier atoms. The final refinement included isotropic displacement parameters for all hydrogen atoms. CF3 group is disordered and modeled with two occupancies. The final R-index was 3.8%. A final difference Fourier revealed no missing or misplaced electron density. Pertinent crystal, data collection and refinement are summarized in Table XRAY-EX27.

Single Crystal X-Ray Analysis for Example 161.

The compound of Example 161 was found to be 7-{(1S)-1-[1-(2,4-difluorophenyl)-1H-1,2,3-triazol-4-yl]propyl}-5-[2-(trifluoromethyl)pyrimidin-5-yl]-7H-pyrrolo[2,3-d]pyrimidin-4-amine.

Data collection was performed on a Bruker APEX diffractometer at room temperature. Data collection consisted of omega and phi scans. The structure was solved by direct methods using SHELX software suite in the space group P2₁. The structure was subsequently refined by the full-matrix least squares method. All non-hydrogen atoms were found and refined using anisotropic displacement parameters. The hydrogen atoms located on nitrogen were found from the Fourier difference map and refined with distances restrained. The remaining hydrogen atoms were placed in calculated positions and were allowed to ride on their carrier atoms. The final refinement included isotropic displacement parameters for all hydrogen atoms. Molecules in asymmetric unit arranged in a pseudo-symmetry relationship. Both molecules in the asymmetric unit have the same chirality. Analysis of the absolute structure using likelihood methods (Hooft 2008) was performed using PLATON (Spek 2010). The sample was assumed to be enantiopure; the results indicate that the absolute structure has been correctly assigned. The final R-index was 4.9%. A final difference Fourier revealed no missing or misplaced electron density. Pertinent crystal, data collection and refinement are summarized in Table XRAY-EX161.

Single Crystal X-Ray Analysis for Example 162.

The compound of Example 162 was found to be 7-{(1R)-1-[1-(2,4-difluorophenyl)-1H-1,2,3-triazol-4-yl]propyl}-5-[2-(trifluoromethyl)pyrimidin-5-yl]-7H-pyrrolo[2,3-d]pyrimidin-4-amine.

Data collection was performed on a Bruker APEX diffractometer at room temperature. Data collection consisted of omega and phi scans. The structure was solved by direct methods using SHELX software suite in the Monoclinic class space group P2₁. The structure was subsequently refined by the full-matrix least squares method. All non-hydrogen atoms were found and refined using anisotropic displacement parameters. The hydrogen atoms located on nitrogen were found from the Fourier difference map and refined with distances restrained. The remaining hydrogen atoms were placed in calculated positions and were allowed to ride on their carrier atoms. The final refinement included isotropic displacement parameters for all hydrogen atoms. Analysis of the absolute structure using likelihood methods (Hooft 2008) was performed using PLATON (Spek 2010). Assuming the sample submitted is enantiopure, the results indicate that the absolute structure has been correctly assigned. Absolute configuration confirmed as opposite to other single enantiomer resolved. The final R-index was 5.8%. A final difference Fourier revealed no missing or misplaced electron density. Pertinent crystal, data collection and refinement are summarized in Table XRAY-EX162.

Ussing Chamber Electrophysiology Assay of CFTR Potentiation in CF Bronchial Epithelial Cells

Primary cystic fibrosis human bronchial epithelial (CF hBE) cells were expanded and cultured according to published methods (Neuberger et al., Ch. 4 of Cystic Fibrosis, Methods in Molecular Biology vol. 741, pp. 39-54 (2011)). Well-differentiated cells (>30 days at air/liquid interface) on Snapwell filters (Corning Costar, cat. no. 3801) were mounted in Ussing chambers (Physiologic Instruments, Inc., San Diego, Calif.). F508del/F508del cultures were assayed at 27° C. and G551D/F508del cells were assayed at 35° C. HEPES buffered physiological saline (composition (in mM): 137 NaCl, 4 KCl, 1 MgCl2, 1.8 CaCl2, 10 HEPES Na) was used in both apical and basolateral chambers. Chambers were bubbled with air to promote mixing and the voltage was clamped to zero. Amiloride (30 uM), forskolin (10 uM), test compound (4 increasing concentrations), and CFTRinh-172 (20 uM) were added sequentially with 20-25 minutes between additions. Short-circuit currents were acquired and analyzed using LabScribe2. Test compound responses were scaled relative to responses for DMSO (0%) and the maximal response of a positive control potentiator (100%).

FRT Ion Flux Assay of F508del CFTR Potentiation

Fischer rat thyroid (FRT) cell lines stably expressing recombinant F508del V470 CFTR and halide-sensitive yellow fluorescent protein (Pedemonte et al., J. Clin. Invest. 115(9) 2564-71 (2005)) were seeded at 25,000 cells/well in 50 uL/well of culture medium into black-walled, clear bottom tissue-culture-treated 384-well plates (Corning, cat. no. 3712). After one day, the cells were pre-incubated at 270° C./5% CO₂ for 16-24 hours. The cells were then washed with dPBS and treated with forskolin (20 uM) and test compound for 30 min by addition of 20 uL of compound dilution buffer (dPBS containing forskolin and test compound). Plates were loaded into FLIPR384 fluorescence imaging plate reader (Molecular Devices). After an initial fluorescence reading, iodide buffer (25 uL) (composition (in mM): 137 NaI, 1.5 K₂PO₄, 8.1NaH₂PO₄, 2.7 KCl, 0.5 MgCl2, 1 CaCl2) was added and a second fluorescence reading was made after approximately 21 seconds. Data treatment involved division of the second fluorescence reading by the initial fluorescence reading, then scaling of the resulting normalized endpoint fluorescence with respect to the responses for DMSO (0%) and a positive control potentiator (100%).
